Patent DE-4329926-A1 (DE)
Title: Screen brightness control stabiliser for photographic print prodn from CRT source - uses video input signal selector switch, when video source is not in blanking-out mode
Inventor: CONSTABLE DOUGLAS WILLIAM
IPC: B41B21/30
Filed: 1993-09-04
Abstract: A video source (10) generates an image representing video input signal and is coupled to the stabilising system by a DC voltage. A switch (12) selects the video input signal, when the video source is in non-blanking-out mode. It selects a reference voltage, when the source is in a blanking-out mode. To the switch and CRT (20) is coupled an amplifier (13) for the video input signal. Shutter control (8) and switch signal gate (9), coupled to the switch, receive the blanking-out signal for CRT screen image erasing. Switches (24) are coupled to the amplifier output, a voltage storage capacitor (25), and eraser (9), and are made on application of the blanking out signal. USE/ADVANTAGE - For image brightness control of CRT screen photocopier, with uniform brightness independent of temp. variation, and component ageing.

Title: Roof module for a motor vehicle
Inventor: KNOLL PETER PROF DR ING
IPC: B60R11/00
Filed: 1993-09-04
Abstract: A device for a motor vehicle is proposed which has an arrangement of one or more sensors for receiving or transmitting optical and/or electromagnetic radiation in a common roof module. The roof module is arranged in the region of a window pane of the motor vehicle at a point which causes as little disturbance as possible. The sensors are aligned in such a way that radiation acting on them from outside through the window of the motor vehicle can be intercepted or they can transmit their radiation outwards. A preferred situation for the sensors is the region of the windscreen, which is cleaned by the windscreen wipers. <IMAGE>

Title: Computer control of spinning plant - has fully instrumented machines providing operational state signals to data store which feeds computer programmed with expert systems to calculate correction values for optimum plant operation
Inventor: MEYER URS PROF DR
IPC: D01H13/00
Filed: 1993-10-10
Abstract: The technologically important operating parts of spinning machines are monitored by sensors and recorded in a data store (20). The operation function for each part is stored in a further data store (22). The initial state and the state at predetermined time intervals of each part are analysed and compared. They are checked against nominated limiting values in a computer (24) and the required correction is calculated. Pref., all machines in a spinning plant, e.g. bale openers, cleaning machinery, cards, draw frames, combers, roving frames and ring frames, are fully instrumented with sensors which measure all the technologically significant values and report them to a data store (20). Input can also be made from human observations through a suitable interface. USE/ADVANTAGE - For computer control of an entire spinning plant from bale opening to yarn spinning. The system is flexible and permits the use of a variety of man/machine interfaces and the use of expert systems for running the plant.

Title: Single and multiple electrolytic cells for deionising aq. solns.
Inventor: NEUMEISTER HERBERT
IPC: C02F1/469
Filed: 1994-05-30
Abstract: Described is an electrochemical cell for the deionization of aqeuous solutions, the cell being equipped with an inlet and outlet for the solution to be deionized, plus supply and discharge pipes for the brine flow. The cell is also equipped with an ion exchanger and with electrodes linked on the inside to electrode spaces between which, separated by membranes, a brine space is located. The aim of the invention is to provide an electrochemical cell of this kind which can be controlled and regulated directly by means of the applied electric field and the applied electric current. To this end, the brine space is directly adjacent to the electrode spaces and the electrode spaces and the electrode spaces are filled with ion-exchange material, the cathode space containing an anion exchanger and the anode space containing a cation exchanger. In addition, the electrodes are in direct contact with the anion-exchange resin and cation-exchange resin beds. Multiple electrolytic cells consist of at least two cells of the type described which are disposed next to each other. Either the electrode spaces of the same type of electrode or the electrode spaces of different electrodes are located next to each other and have a common electrode, the electrode spaces being separated from each other by a bipolar membrane or a bipolar electrode.

Title: Ethylene oxide gas converted to ethylene glycol in closed circuit system
Inventor: DRZEVITZKY BERND DIPL ING
IPC: A61L2/20
Filed: 1994-05-31
Abstract: A process and device are disclosed for disposing of ethylene oxide gas used for sterilising objects within a vacuum sterilisation chamber (5) by means of a pump (10) connected to the sterilisation chamber (5) that supplies ethylene oxide after sterilisation to a gas scrubber (15) that works with acids. The sterilisation chamber (5), the pump (10) and the gas scrubber (15) form a closed gas circuit; the pump (10) continuously delivers ethylene oxide from the sterilisation chamber (5) to the gas scrubber (15), and the exhaust gas from the gas scrubber (15) is supplied to the sterilisation chamber (5). The ethylene glycol formed from ethylene oxide in the gas scrubber (15) is continuously withdrawn from the gas scrubber (15) and further acids are continuously added to the gas scrubber (15) depending on its acid consumption. This cycle is maintained until the residual concentration of ethylene oxide in the gas circuit falls below a predetermined level. An inert gas source (48) is preferably connected to the gas circuit (5, 35, 10, 39, 15, 40, 38) to supply inert gas to the gas circuit in a controlled manner when the ethylene oxide elimination causes the gas circuit inner pressure to fall, the pressure drop in the gas circuit being adjustable.

Patent DE-4431202-A1 (DE)
Inventor: KNOP REINHARD
IPC: D21H23/56
Filed: 1994-09-02
Abstract: There are prior art devices for applying coating material to both sides of paper or cardboard webs (8) having two adjacent pressure rollers (2, 3) in a frame (1), between which there is a nip (7) through which the paper or cardboard web (8) is taken. On each of the pressure rollers (2, 3) there is an application and metering system (10, 11) which applies a metered film of coating material to their jackets which is then transferred in the nip (7) to the web (8). One of the two pressure rollers (3) is supported so that its circumference can be moved toward the other. According to the invention, in order to adjust the position of the nip (7), one of the two pressure rollers (3) is fitted with a component to move in the nip (7) towards the shared tangent to the two pressure rollers (2, 3). This makes it possible with different web and coating materials to stabilize the withdrawal of the web from the pressure rollers (2, 3) by altering the belt wrap ratios.

Title: Laundry washing or drying machine control
Inventor: WEINMANN MARTIN DIPL ING
IPC: D06F34/18
Filed: 1994-09-07
Abstract: To control the operation of a laundry washing machine or dryer, according to the load, the charged drum (1) is rotated initially for the motor (4) torque to maintain a constant rotary speed. On acceleration, the motor (4) torque required is registered to spin the charged drum (1). The control electronics (5) gives the quotient of the difference value of the two torques and the angular acceleration of the drum (1), for a quotient which is proportional to the inertia of the drum (1), and increases proportionally to the laundry charge. A setting value for the control is derived from the quotients.

Title: Method of controlling games machine operated by coins, tokens or similar payment elements
Inventor: BETHKE DIETER
IPC: G07F17/32
Filed: 1994-11-04
Abstract: The method involves generating random numbers until they are recognised as valid by a central controller. The symbol indicators are then stopped at the corresp. symbols or symbol combinations, which are then characterised as winning or non-winning combinations. If appropriate, the contents of the win memory and its associated display are increased. For defined time periods and/or for certain game plays, a larger number of permissible random numbers is associated with at least one symbol indicator and its stop positions and/or with individual symbol combinations than with other symbols, stop positions or entire symbol combinations.
